Abstract: The device for thickening and demolishing floating matter from the surface of wastewater in a clarification basin (1), comprises a first reception device (20) for the reception and conveying of floating material in a thickening channel for thickening the floating material, and a second reception device for the reception of thickened floating materials, where the thickening channel is communicatively connected with the clarification basin. The thickening channel is stationary arranged within or external of the clarification basin. The device for thickening and demolishing floating matter from the surface of wastewater in a clarification basin (1), comprises a first reception device (20) for the reception and conveying of floating material in a thickening channel for thickening the floating material, and a second reception device for the reception of thickened floating materials, where the thickening channel is communicatively connected with the clarification basin. The thickening channel is stationary arranged within or external of the clarification basin. The thickening channel and the first reception device are movably mounted on a scraper bridge of the clarification basin. The thickening channel and the reception device are arranged along the scraper bridge. The thickening channel consists of first and second side walls (41, 42) that submerge in the wastewater of the clarification basin. The thickening channel has transverse walls running vertically to the side walls. The first transverse wall is arranged on an end and/or a second transverse wall is arranged on another end of the thickening channel. The second transverse wall is formed through the second reception device. The thickening channel comprises a base arranged under the surface of the wastewater. The base is equipped with a slope. The base limits a section of the thickening channel, releases an opening and is arranged near to an inlet of the thickening channel and the opening is formed near to the second reception device. A further reception device is arranged in the thickening channel, which has a length of 2-5 m. The first and/or the second reception device are a skim drain adjusting itself on the water level with a pump, or a skim screw or a paddle work. The pump is connected with the inlet of the thickening channel in such a way that the floating material influxes on the second reception device. The second reception device is arranged on an end of the thickening channel opposite to the inlet. The first sidewall of the thickening channel is an introduction barrel passing up to the reception device. The first and second side wall pass to each other in an angle and the round-shaped thickening channel is arranged parallel to first reception device. The first and second side walls are concentrically arranged. The flowing is carried out tangentially in the thickening channel.
